The purpose of this paper is to compare the effects of paper-based and computer-based concept mappings on computer hardware achievement, computer anxiety and computer attitude of the eight grade secondary school students. The students were randomly allocated to three groups and were given instruction on computer hardware. The teaching methods used for each group were the conventional method, paper-based concept mapping and computer-based concept mapping. At the end of a 4-week instruction, posttests were administered to assess computer hardware achievement, computer anxiety and computer attitude of the students. The findings indicate that paper-based and computer-based concept mapping strategies produce better results than the conventional method. However, the effects of paper-based and computer-based concept mapping strategies were not significantly different. 相似文献

Our attitude to computers is informed by what the author calls the Computer Literacy Credo: a pervasive belief that working with computers requires—and creates—a new type of human mind. But there is no empirical evidence for this belief. The Computer Literacy Credo is grounded not in fact, but in a millennarial hope typical of Western culture that one day we will be able to bridge the schism between reason and passion, between the abstract and the concrete, between science and art, between the artificial and the natural, between responsibility and freedom. Our faith in computers reflects a rather new version of this old dream, in that this time the schism is healed by technological means. 相似文献
